Here's my quick Illustrator rendering of what I'd like to see come out of MW San Francisco. Ports in front, G4 under the hood, simple elegant and functional with a small footprint. Sure, a built-in coffee maker, cold-fusion reactor and glistening chrome supercharger would be nice, but let's leave something for the accessory makers to sell us.
Just remember... If Apple's legal brute squad comes a knockin', you don't know me and you never saw this rendering.
